+AllTrials Transparency Index

Ranking the world’s biggest pharmaceutical companies by their policies on clinical trials transparency

About this site

In medicine we use the results of clinical trials to make informed treatments about which treatments work best. But there is a problem: the results of clinical trials are being routinely and legally withheld from doctors, researchers, and patients. This is a problem for industry sponsored trials, and for trials funded by governments and charities.

We have ranked all the world’s major drug companies, and a selection of smaller firms, by the commitments they make to clinical trials transparency. Next, we will be ranking the policies of non-industry trial funders. You can find out more about unreported clinical trials at AllTrials.net.
